Vorschrift

To 60 mL of water, 15.8 g (90.8 mmol) of sodium hydrosulfite, 50 mL of ethyl acetate, 10.0 g (45.5 mmol) of 2,6-di-tert-butyl-1,4-benzoquinone and 1.04 g (4.57 mmol) of benzyltriethylammonium chloride were added and the mixture was stirred for 1 hour at 25° C. The reaction mixture was subjected to liquid-liquid separation and the aqueous layer was discarded. The organic layer was washed with 20 mL of 10% aqueous sodium chloride and the solvent was distilled off under reduced pressure to give 2,6-di-tert-butylhydroquinone.
